After the failure of the bead on my raceking during the Spain CTC when it unraveled I was sent a replacement by the store.
In the last couple of weeks the new one has started losing air. Further examination this morning showed the bead on this one is also coming unraveled.....
I can't find any similar issues on the internet, I've checked the rim and it's fine.
So, anyone else had a problem with them? And what's a good fast alternative.
Had this with 2 x-kings. Replaced by crc. I think the inside edge of the stans arch mk3 rim is square rather than rounded and run at lower pressures and add a bit of grit just cuts its way through the bead. And conti beads dont look very substantial to start with!
I had a couple of Knards go the same way. Suspect the pressure was to low, causing the tyre to creep relative to the rim. Going tubeless sorted the problem.
I've stuck with the x kings on the back for now till they have worn out and running them a little bit harder. I had the rim replaced too, the inside edge of the last arch felt like a used junior hacksaw blade!
As Hux says, i had this exact problem. I think its when u run them lower pressures grit gets in there and wears em away. I now run them harder too. I have got a Maxxis Ardent now on my new wider rim and this is so good. Its very grippy but not super draggy on the tarmac, think id move to these once all my x kings have gone! Oh and iv just got a wtb ranger for the rear but its only a 2.2 which i reckon will be fast for stuff like the BB200
Shame about the xkings coz i really like them but no good if you have to use a cable tie to get ya home.
Cheers guys, found a racing Ralph in the tyre pile in the garage so that's gone on for now.
I'll strip it after tomorrow's ride and see if the bead is damaged and double check the rim.
